2001 Ford Mustang GT engine complaints

Filed Nov 28, 2006 · Engine · 70,000 miles · NY

I don't know much about the mechanics of cars, but a spark plug blew out of my 2001 mustang gt causing a loud repetitive noise and a notable loss of power. It was still under the 30 day/3000 miles used vehicle warranty and it was fixed at no charge to myself. The same thing happened again a week later and I was told (in the best words that I can describe it) the threading in the hole of the part of the engine that the spark plug screws into, would no longer hold the spark plug and that the engine needed to be sent to a machine shop to bore the hole in deeper costing a around $3000.00.

I started my vehicle in the morning and I heard a loud noise in the engine. I left the car like that and called my mechanic. When he checked the car, he found out that the spark plug was loose, he just put back. A couple of months later, I heard the noise in the engine again, I knew what the poblem was so I put the plug back in. Some months later (12/04) I had the same problem, but this time the plug wouldn't tighten, so I called my mechanic again. He checked the car and found out that the thread in the spark plug hole had stripped. I bought a spark plug thread kit and he was able to fix the engine, but the engine didn't perform the same.

At 7,853 miles, the engine started making a knocking noise. Upon checking the dip stick, the stock was twisted out of shape, giving a reading of more oil than needed. The first service center that I took the car to stated that the car had 1 quart of oil, and could burn 1 quart of oil per 1,000 miles when new (nowhere was this noted in owner's manual, which recommends oil changes every 5,000 miles). Oil change was performed, which did not remedy the situation. The next dealer that the car was taken to identified that the #8 bearing was worn, which required the engine to be replaced. Ford would not honor their warranty, nor would the dealer or the customer service center in michigan answer any of the owner's questions, except that they would not cover the engine. Owner was left purchasing a new engine on their own.
